I worked on the grill block again last night. Its really starting to get near to its end form.
Here is a shot of the actual pushrods I used. I picked them up at a local hobby store. They're made for radio control airplanes. By the time I had sanded mine down those ridges were completely gone on the grey pieces. I only sanded it down in the area of the bend.
This is the first pushrod mounting piece. As you can probably tell, there isn't a ton of extra space to work with.
I had to file down the connecting piece between the two rods so it would fit around the hardware.
This is the other pushrod mounting point. It will make the 90 degree bend that is needed to get the pushrod out of the way of the actuating door flap.
And finally I threw the pushrod in to show how it'll be mounted.
